71024S12TYG8 Equivalent & Substitute Parts

Part Overview

The 71024S12TYG8 is a 1Mbit asynchronous SRAM manufactured by Renesas Electronics Corporation in a 32-SOJ surface mount package. This volatile memory IC operates with a 12 ns access time and write cycle time, supporting parallel data interfaces across a 128K x 8 memory organization. The part is actively produced and ROHS3 compliant, making it suitable for legacy and current industrial applications requiring high-speed parallel memory access.

Substitute parts are identified when equivalent memory capacity, organization, interface type, and package specifications are maintained while allowing variations in access time performance and operating temperature ranges within acceptable engineering parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 71024S12TYG8 is determined by the following mandatory parameters:

• Memory capacity and organization (1Mbit, 128K x 8)
• Memory interface type (Parallel)
• Package specification (32-BSOJ, 0.300" width)
• Supply voltage range (4.5V ~ 5.5V)
• Mounting type (Surface Mount)
• Compliance certifications (ROHS3, REACH Unaffected)

Substitute parts may vary in access time performance and operating temperature range provided all mandatory parameters remain equivalent. The identified substitutes maintain full electrical and mechanical compatibility with the primary part.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full ROHS3 compliance with REACH unaffected designation. Selection between the primary part and substitutes depends on application-specific timing and temperature requirements.

The 71024S12TYG8 and IS61C1024AL-12JLI both provide 12 ns access and write cycle times. The 71024S12TYG8 operates within a 0°C to 70°C temperature range, while the IS61C1024AL-12JLI extends operation to -40°C to 85°C. The 71024S15TYGI8 provides extended temperature operation (-40°C to 85°C) with relaxed timing specifications at 15 ns access and write cycle times.

Frequently Asked Questions (FAQ)

Q: Can the 71024S15TYGI8 replace the 71024S12TYG8 in all applications?

A: The 71024S15TYGI8 maintains identical memory capacity, organization, interface, package, and voltage specifications. The 15 ns access and write cycle times are slower than the primary part's 12 ns specification. Substitution is valid only for applications where the extended timing does not violate system performance requirements.

Q: What is the difference between the Renesas 71024S15TYGI8 and ISSI IS61C1024AL-12JLI?

A: Both parts provide 12 ns timing performance and extended temperature operation (-40°C to 85°C). The primary difference is manufacturer: Renesas Electronics Corporation versus ISSI. All electrical and mechanical parameters remain equivalent.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 32-BSOJ package with 0.300" width and surface mount configuration, ensuring mechanical and electrical pin compatibility.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range does not prevent substitution. The 71024S12TYG8 operates 0°C to 70°C, while both substitutes extend to -40°C to 85°C. Applications operating within the primary part's temperature range may use any substitute. Applications requiring extended temperature operation must use IS61C1024AL-12JLI or 71024S15TYGI8.

Q: What packaging formats are available for these parts?

A: The 71024S12TYG8 is supplied in Tape & Reel format. The 71024S15TYGI8 packaging format is not specified in available data. The IS61C1024AL-12JLI is supplied in Tray format. Verify packaging requirements with procurement specifications before ordering.
